Excellent. Thanks, it's what I thought as well. My T4 is dialed in for every type of track condition using the ball diff so I was leaning towards it. Now if my local shops would just get the outdrive bearings for the Tranny case, then I could have 2 complete Tranny's to swap as needed. This means I will be tearing down the Gear diff to use that case for the ball diff.
